Randomness can be certified in energy-constrained semi-device-independent scenarios
Shashank Kumar Ranu, Lewis Wooltorton, Alastair A. Abbott +1
The prepare-and-measure framework based on energy constraints offers a practical middle ground between fully device-dependent and device-independent quantum cryptography. The only…

Self-testing Quantum Supermaps
Victor Barizien, Cyril Branciard, Alastair A. Abbott +2
By certifying quantum operations from measurement statistics directly, without any assumption on the internal workings of the devices involved, self-testing enables a uniquely reli…
